LYMAN R. BLAKE, OF FORT WAYNE, INDIANA.

Specification forming part of Letters Patent No. 132,794, dated November 5, 1872.

To all whom it may concern:

Be it known that I, LYMAN R. BLAKE, of Fort Wayne, in the county of Allen and State of Indiana, have invented an Improvement in Lasting and Nailing Boots and Shoes 5 and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enaable those skilled in the art to practice it.

In lasting boots and shoes preparatory to uniting their uppers and vamps upon sewing-machines, it is customary to temporarily fasten the inner sole and vamp together by means of lasting-tacks, the point of the tack being driven against a metal-faced last, by

which the points are turned and clinched. The points of such lasting-tacks, in turning or clinching, are left upon the surface of the inner sole, and are very troublesome when the boot is worn, the soles of stockings catching upon them and tearing; and, in nailing boots and shoes upon lasts, the

points of the nails bend or clinch against the face of the last and form troublesome points projecting into the shoe, and injurious both to' the feet and to the stockings.

The object of my invention is to remedy these defects by so driving the nails that, in lasting or soling by nailing, the points of the nails will upturn and re-enter the sole, occupying positions where they are harmless. To efiect this, I use ametal-faced last, the outer surface of which is grooved or serrated, and in driving the nails, when a nail-point strikes the metal, the point is not only turned laterally but is turned up, and the point enters the surface of the leather from which it protruded. It is in this constructionof a last and method of upturning the points of nails in lasting and nailing soles that my invention consists.

The drawing represents a last embodying my invention, and a section of a sole and upper united by nails upon a last.

adenotes a last; b, the plate upon the soleface thereof, this plate covering either the whole face of the last, or the portionsnear the edge thereof. 0 denotes the upper, dthe outer sole, and e the inner sole of the boot. The surface of the sole-plate is serrated, corrugated, or grooved, as seen in the drawing, and as each nail is driven its point, when it strikes the metal,enters some one of the grooves or recesses f, and by the form thereof is curv ed and turns back and runs in the opposite Witnesses:
